Find object by id in array Javascript

In this tutorial, we will learn how to use JavaScript to find an object in an array by its id. This is a common task when working with data structures that store multiple objects, such as JSON arrays. We will use the `find()` method, which returns the first element in the array that satisfies a given condition.
